SPANCO - Gantry Cranes Play Role in Seattle Light Rail Project
One of the largest suppliers of light rail mass transit vehicles in the northern United States operates as a ‘set-up site’ manufacturer. Once awarded a contract, a building is located, they set up their equipment and a production process, and then move on to the next site as another contract becomes available. Skender Nezaj, production manager with the company is responsible for overseeing site set-up, and ensuring that production is efficient.
In 2007, Skender was asked to head up a major project in Seattle, Washington. His company was awarded a contract to build 35 light rail cars for the regional transit provider in Central Puget Sound. The cars will eventually operate as part of the City of Seattle’s new light rail transit system that will connect the city of Seattle to SeaTac Airport. Skender researched the area and chose an old Boeing 787 production plant north of Seattle as the set-up site. As Skender set up the production process, he chose SPANCO Gantry Cranes to solve his challenging lifting problems.
The production of the light rail cars happens in sections. Drive trains and internal components are assembled in the facility through a long series of stations. A 7 ½ ton SPANCO PF Motorized Gantry Crane with a 20’-0” span and a 20’-0” underbeam height is used to provide ergonomic and efficient movement of the large drive train chassis as they move through the assembly process.
Once completed, fiber glass car shells imported from Japan are mounted onto the components and drive train chassis with the help of two 10 Ton SPANCO T-Series All Steel Adjustable Gantry Cranes. The cranes are used in tandem with a webbing sling to lift the shells onto waiting chassis.
When asked how SPANCO Gantry Cranes have helped him on the project, Skender states “Portability of equipment is a significant factor for the Seattle Light Rail Project. SPANCO Gantry Cranes have really helped our business because of their portability; we can break them down with little or no effort and take them with us. The gantries have truly helped our productivity. The building we are in now did not have cranes in it, so we installed gantry cranes for the production line. The SPANCO gantry cranes offer quality, met our budgetary needs, and were delivered on time. They were simple to install, were extremely rigid, and had a solid base. Technical support was also easy to get to”
Skender has been very pleased with the role that SPANCO Gantry Cranes have played in the Seattle Light Rail Project. He has even recommended SPANCO Gantry Cranes to other “set-up site” project managers within his company.
SPANCO sells a wide range of motorized gantry cranes with pre-engineered spans of up to 60 feet and capacities of up to 15 tons. Our motorized gantry cranes are trackless and motorized directly on the floor. Consider a SPANCO Motorized Gantry Crane as an economical addition to your production facility or process.

SPANCO - Wall Mounted Jibs Provide Lifting Supplement for Leading Manufacturer of Mobile Cranes
A leading manufacturer of mobile cranes operates a 58,000 square foot manufacturing facility in southeastern Pennsylvania. Assembly of the large cranes takes place in an individual building that is outfitted with large 30 Ton overhead cranes. The large mobile cranes are assembled as they move on a conveyor system through different staging areas. Each staging area serves as a sub-assembly for a different part of the mobile crane. Sub-assembly areas might include gearbox build-up, valve systems, transfer case build-ups, radiator build-ups, or engine frame staging.
During the set-up of the assembly line, management explored possible material handling solutions. Originally, a large freestanding I-beam workstation crane was considered. This solution became problematic because it interfered with the overhead crane. The shop manager suggested the possibility of using wall mounted jib cranes because of the ability to fold them out of the way. Turning to his local overhead material handling dealer, his dealer recommended SPANCO wall mounted jibs because of their ease of use and quality build. After reviewing what SPANCO could provide, the shop manager invested in six 1 Ton capacity SPANCO 300 Series Wall Mounted Cantilever Jib Cranes. The jibs were mounted to the existing support structure and were placed in key sub assembly areas where overhead lifting was a critical need.
One sub assembly area is the "super-structure engine assembly." In this area the mobile crane’s engine is pieced together and tested. Once the worker in this area has completed an assembly, the jib allows him to lift the assembly with ease. It is moved from his workstation out to the main assembly conveyor so that it can be installed on to the chassis. The jib allows him to lift up and over changing floor obstacles within the radius of the jib. Having the jib in his workstation means he doesn’t have to wait to use the large overhead crane.
SPANCO Wall Mounted Jib Cranes are the perfect lifting supplement for large overhead facility cranes.
